No one likes to have low water pressure inside your house. Since we need water to do everyday chores like dishes, it is crucial that the water pressure is good.

However, in some cases, water pressure drops due to many different causes that affect your plumbing. And, sometimes, the problem is only located on the top floor.

Now, when it comes to determining the cause of this kind of problem, you need to know exactly where the pressure is low. In some cases, only the upstairs bathrooms have low water pressure while other rooms with faucets are just fine.

On the other hand, every possible faucet and water supply line is suffering from low water pressure on the top floor.

Anyhow, there are a couple of things you can do to increase it and get rid of the low water pressure. Let’s take a look.

Low Water Pressure Upstairs – Only One Faucet

As we already mentioned, the problem might be located only in one faucet. If that’s the case, then you are not in big trouble.

1. Clogged Pipe

Namely, the most common cause of low water pressure in only one faucet upstairs is most likely clogged pipe. This can happen due to the fact that pipes are usually the best place for all sorts of build-ups to gather and create a clog.

Simply put, if you live in a place where the water is rich with minerals, then you will most likely have this kind of problem. Also, in case you have steel pipes in your water system, then the corrosion build-up can lower the water pressure as well.

So, the most common cause of the clog inside your pipe is:

  • Mineral Build-ups
  • Corrosion Build-ups

They are both easily cleaned so you don’t really have anything to worry about. Just use a bit of baking soda and vinegar solution and cleanse the pipes. This will result in an increase of the water pressure and you will be good to go.


2. Faulty Showerhead or Faucet

This is also one of the most common causes of low water pressure on the top floor bathroom. The first thing that you need to check is inside of the faucet and the showerhead as well.

In some cases, showerheads and faucets will be full of dirt or other kinds of build-ups, and, that will result in a loss of water pressure at that particular faucet. That being said, the only logical thing to do next is to remove the faucet or the shower head and clean them properly.

After you are done, you will need to reinstall them back on the water supply line and everything will be back at normal. 

However, in some cases, you will need to change the whole faucet or the showerhead. That mostly depends on how old are these water line endings. If you have an old faucet or an old showerhead, then replacing it would be the best option.

Low Water Pressure on Top Floor – The Whole Floor

Sometimes, the loss of water pressure will occur only on the top floor. While downstairs water pressure is normal, the top floor will suffer from a low water pressure. Most of the people wonder why?

Well, there are a couple of reasons for this kind of problem to happen. And, the most common ones are:

  • Blockage of the Pipe on the Top Floor
  • Area problems – Low water pressure in an Area

1. Pipe Blockage

Now, we’ve already mentioned that clogged pipe is the cause of low water pressure on the top floor, but on only one faucet. This problem, however, is located at the beginning of the water supply line on the top floor.

And, that’s why it lowers the water pressure on all faucets that are installed on the top floor. So, how can this happen?

Well, the blockage can be caused by many different things. For example, if you live in a bit older house, then the water line constriction is made out of steel pipes. And, these steel pipes are long overdue so they have all sorts of build-ups inside them.

That’s why the pressure is low on your whole top floor. However, the problem might be located at the pressure regulator as well.

In case you have a special pressure regulator only for the top floor, then that could be the cause of low water pressure. Keep an eye on that as well.

2. Low Water pressure Area

In certain places, the water pressure is constantly low. You can check with your neighbors and see if they also have this kind of a problem. But, if the pressure is low in the whole area, how is it that you only suffer from low water pressure on the top floor?

Well, the answer is quite simple. Namely, the amount of pressure that pushes water through the pipes is only enough to supply the ground floor.

As we all know, water supply line starts from the ground floor, and that’s why there is only good water pressure on that floor.

But, when it comes to the top floor, the water flow drops since there isn’t enough pressure to push the water through the pipes and reach top floors. This happens usually in places where the water is brought via water supply line from the lake or a river.

However, that doesn’t have to mean that you will constantly have low water pressure on the top floor. But, when it happens, there’s nothing you can do except to wait until the professionals do their job and fix the problem.

Conclusion: Low water Pressure On Top Floor

Dealing with this kind of problem isn’t always an easy task. But, being able to do something surely is enough. All in all, low water pressure on the top floor is not that common problem, but when it occurs, you should know what to do and how to fix it.

We surely hope that this little guide helped you to determine the problem and to fix it as well.
